Abstract

PROBLEM TO BE SOLVED: To reliably detect feed failure of a longitudinally chained terminal in a terminal crimping machine or the like. SOLUTION: This abnormality detecting mechanism is composed of a roller 24 ascendable-descendable along a projecting part and a recessed part of a chained terminal 5, a proximity dog 17 driven by the roller, an elastic member 22 to energize the proximity dog in the roller direction and a proximity sensor 28 arranged so as to be opposed to the proximity dog. The proximity sensor 28 is fixed to a sliding block 29, and a cover 27 is arranged on a base frame 13 holding the proximity dog 17 so as to be freely ascendable-descendable, and the sliding block 29 can be mounted on an demounted from the cover. The projecting part of a first terminal of the longitudinally chained terminal 5 is detected by the sensor 28, and next, the recessed part of the first terminal is detected by the sensor 28, and next, a projecting part of a second terminal is detected by the sensor 28, and when these are not detected in a single cycle, it is judged that terminal feed is abnormal. The projecting part may be a rear side crimp piece, and the recessed part may be a front side crimp piece.

3 2 is located just below the roller 24. This causes the roller 24 to rise again, and the proximity dog 17 turns on the sensor 28 (48 in FIG. 10). While the terminal 40 is normally sent, the on-off-on cycle of the sensor 28 is repeated. When the terminal feed is stopped in the state of FIG. 8, the on-off-on operation of the sensor 28 is interrupted, so that the sensor 28 detects an abnormality as indicated by 47 in FIG. Stops. When the sensor 28 is turned on in FIG. 9, terminal crimping is performed as indicated by 50 in FIG.

大する。As described above, according to the present invention, a defective feeding (no feeding) of the vertical chain terminal can be detected, so that a defective product without crimping the terminal can be prevented from flowing out, and a defective product can be prevented. The number of man-hours for reworking due to the occurrence is reduced. Further, since the sensor can be attached / detached with one touch, the workability of attaching / detaching the sensor is improved when the applicator of the crimping machine is replaced (claim 2). Further, since the sensor is operated by utilizing the height difference of the terminals, it can be applied to various terminals and the versatility is expanded.
